Quite a few of us did hard time at West Milton in New York. Nuclear Power Training Unit Ballston Spa was one of three sites in the 70's and 80's for prototype training for us nuclear trained personnel. I personally qualified at MARF (S7G) and served on staff at the Trident prototype (S8G). Others qualified at S3G and D1G, all visible in the photos below.
